Not only does your automatic sensor data make your weather forecast more accurate, but we also incorporate user-reported weather conditions to train and correct our models. Our forecast accuracy improves as more users join!

Note: Temperature forecasts are for North America only right now. We will be adding more locations as users request them. Send us an email to let us know you're interested! software@cumulonimbus.ca.

Hopefully will help out one day. This program doesn't seem to be using much battery or other resources to a point that it's noticeable. I'd like to see more of how the data is implemented in weather predictions etc.. I'm surprised that this data isn't already taken without our knowledge by Google or the government. Ehh who cares? Still, I love the science.

Decent app I like the idea. Too bad the alerts and forecast features aren't available in my region. Nor are the temperatures (as seen in screenshots) available to me in the Netherlands, so the map is less useful for me. Also the play button doesn't show the reports anymore either.

Great trends information Pressure drop alerts for pending severe weather would be a great addition. Edit/Reply: Thank you for the response! Configuring the sensitivity of the pressure drop alerts would be great for the hard core wx nerds. :-)

Unusual weather not covered App works great, fun to use. However there is no field for "smoke". Right now we are very smoky but not actually on fire; but "wildfire" is the closest report we can do. As well, since the latest update, opening pressurenet also opens the Steam app, I have no idea why.

Hi Andres, I removed the pressures from the map because they were not useful. It's very difficult to adjust the readings to Mean Sea Level Pressure - that's not real weather data so I removed it. Thanks for your feedback.
Edit: We are using the pressure data that you send in our live weather forecasts! That's what we show on the map now.

Hi Matthew, thanks for the feedback! We do have pressure drop alerts (you can enable them in Settings) but they are not yet tied to pending severe weather. Any rapid shift in pressure tendency will issue an alert - sometime this will be a big storm, but it might also just be a bit of rain. Thanks!

Hi Jack, the data graph log is still there! If you open the menu on the left of the app - tap the pressure reading in the title bar - it's the first item on the list!
I'm trying to make the UI cleaner for this to be a better weather app. Sorry to have moved this, but it's still there!
Please let me know if you have other issues. Thanks!

Hi, we do not require identity permissions. This was a bug in the beta, sorry about that!
PressureNet's sole purpose is phone pressure data - we use it to make your weather forecast!!
Edit: It turns out that a beta release had a permissions bug with Google Play Services. Fixed now! Source code is here: https://github.com/Cbsoftware/PressureNet

Hi Justin, Thanks for reporting the crash, and we're sorry that this is happening. We'll have it fixed soon so you can try the new features! Thanks.
Edit: I have fixed the issue and sent out the update to version 4.7.1. Thanks, and sorry!

Good concept The concept is a great one, however, it greatly lacks in user base for weather notification, and the idea of sourcing a phone for pressure is a little iffy. Even if gps altitude is enabled I get pretty huge fluctuations as I drive around, so my data is all pretty useless.

Citizen science A great app that allows you to submit atmospheric reading for experts to use and increase our understanding of our planet. I encourage everyone to participate, as it doesn't require technical knowledge and doesn't require any interaction.

A novel and interesting app Not bad at all, and crowd sourcing of atmospheric pressure using smartphones makes sense. I can't get the animation to work. Is this a really useful feature? Why not drop it from the app, or make it go properly. The graph could be improved. Temperature report is inaccurate; needs compensation to account for instrument temperature. 5 stars if these improvements are made.

Great idea, but randomly glitches and drains battery Usually worked great, but once every day or two it would start draining battery at &gt;30% per hour with large increase in battery temperature and the only way to stop the drain was to restart phone. Had to uninstall as a result since it would kill the phone if you didn't catch it in time.

Hi Aaron,
I'm so sorry to hear this! I do notice you're using an older version, have you tried upgrading to 4.6.0 from 4.5.8? Thank you for the bug report, I will work to resolve this immediately if it's still a problem. I have not noticed this behaviour on test devices. Are you using GPS? Please email me, jacob@cumulonimbus.ca. Thanks!

Pretty Good I love in a hilly area next to the California Central Valley. I can use the changing values graphing to track when I came and went from home. Cool. Not so cool is that the altitude is almost never within one hundred feet of accuracy. I am at 1225' now and it showed about 620', which is typical. Wouldn't be good accuracy for, let's say, an aircraft altimeter based on barometric pressure.

Problems seem fixed now. Thanks I've been running this app for a few years and it's done everything it should over that time. However, the most recent update causes my GPS to be opened 100% of the time. I verified this using a battery tracking app. This drains my battery like mad. Please fix and the app gets 5 stars. Running on stock Verizon Galaxy S3. I'll reinstall once this is fixed.

Great concept and a great app! Excellent application for the collection, transmission, and dissemination of local weather conditions. This is the future of meteorology, and the science of weather forecasting will improve tenfold because of it and similar efforts. Maybe one day we will finally be able to conduct detailed analysis of the interior of an active cyclone by feeding 1,000 iPhones into a raging Cat. 4 tornado! It is also a great 'companion' to your registered PWS.! KFLCORAL27

Graham This is perfect. I can send information freely and often. I think i have become an amateur scientist and I feel good about contributing to science in this way. Thank you very much for the new self esteem that you've given me. Beware, I'm going to be hanging around for a long time with you. Thanks again.
